A World War I submarine that sank nearly 110 years ago has been leaking hazardous explosive substances, including TNT, into the North Sea for decades. Oceanographers warn that this issue may worsen over time, not only near this German vessel but also in the vicinity of thousands of similar sunken ships.
The submarine in question is the German UC-30, which sank on April 19, 1917, after attempting to return home due to engine problems and striking a British mine near the Danish island of Rømø. This information was reported by the popular science magazine Popular Science.
